Rock pools are not easy places in which to live. The creatures that live in them must be able to cope with lots of water when the tide is in, and not much water, but lots of light, when the tide goes out.
Things to do!

Have you ever seen a jellyfish on a beach? They don’t look very pretty do they? But in the water, jellyfish are spectacular! They are a bit like floating upside-down umbrellas. Let’s find out about these fascinating creatures. Jellyfish are not really fish at all. They look more like flowers but they really are sea creatures. They are shaped like half of an orange, upside down and can be very small or as big as your dinner plate. Unlike an orange the underneath is not flat, but domed like an umbrella. They are made of a jelly. The jelly is nearly all made of water. If a jellyfish is not in the water, it will very soon die. The hot sun will dry it up very quickly. Around the edge of the bell shape there are little black dots. These are the eyes. The long stringy bits that you can see that look like kite tails are the arms. The arms are the jellyfish’s feelers and it uses them to touch things. The feelers wave gently in the water helping it to move through the water.
The jelly fish has a mouth. The mouth is up inside the dome. The mouth has a little frill over it so that the jellyfish can close its mouth! Beneath the mouth are the fishing lines. These soft pretty ruffles move up and down in the water and catch things for the jellyfish to eat. Some jelly fish glow, a bit like glow-worms. Some people call them the ‘lamps of the sea’. They can make the sea look very pretty at night! Think: it seems strange that a creature, that is not much more than a ball of jelly, can have such and interesting and adventurous life all of its own. Thought for parents/teacher: Is this random chance or evidence of intelligent design? What is the chance, mathematically speaking, of all the necessary facets of such a creature to come together and function perfectly, out of chaos? |
